Weighted data matrix

Is there any support in GaussianMixtures for weighted rows in a data matrix? For example, if I have a dataset with many repeated observations, can I pass in a matrix...

Expose stan::math::hessian and stan::math::hessian_times_vector as methods in the stan::model class

15

#### Summary: The ```stan::model``` class does not currently expose the ```stan::math::hessian``` and ```stan::math::hessian_times_vector``` of the log probability, though in principle it could easily do so in a manner similar to...

Express galaxy locations by interpolating the PSF

1

Currently, we first render the galaxy at the location given by the variational parameters and then convolve with the pixelated PSF. For the same reason that we cannot get sub-pixel...

The ```fsm_util``` code uses ```lidx``` indices, even though it is used both by DeterministicVI and the LogProbability modules. This design relies on the ```ids``` parameterization and the ```lidx``` parameterization having...

Patient symptoms or other estimates of disease severity

**Please describe the dataset you want** Patient symptoms or other estimates of disease severity, disaggregated as finely as possible. **How is it relevant to Covid-19?** Epidemiological simulations that guide policy...

Have script work with python 2 and python 3

1

If python 2 is the system default, the script will fail with an ```OrderedDict``` error.

Right now, ```mcmcse``` throws a lot of errors about highly correlated samples even though I think nothing is wrong.

Make end-to-end tests out of some more complex examples for unit testing.
